SPECIFICATION forming part of Letters Patent No. 611,338, datedSeptember 27, 1898. Application filed September 29, 1897- Serial No.653,438. (No model.)

To aZZ whom it may concern.

Be it known that 1, WILLIAM E. SHARPLES, of Fall River, in the county ofBristol and State of Massachusetts, have invented certain new and usefulImprovements in Spinning-Frames; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

This invention relates to the arrangement of the mechanism forfacilitating the doffing of the bobbins in ring-spinning machines.

The object of the invention is to afford simple, efficient, andinexpensive means for holding the ring-rail down while the full bobbinsor cops are taken off of the spindles and empty ones put on. It is fullyexplained and illustrated in this specification and the accompanyingdrawings.

Figure 1 is a Vertical cross-section of the roller-beam, guideboard,separator-bar, ringrail, spindle-rail, and lower rail of a ringspinningframe with the stopping devices in elevation. Fig. 2 is a back elevationof the parts shown in Fig. 1. Fig. 3 is the same as Fig. 1, exceptingthat the arm that operates the stop-catch is attached to thethread-guidelifting rod instead of the separator-bar. Fig. 4: shows aback elevation of the parts shown in Fig. 3.

In the drawings, A denotes the roller-beam, and J the thread-guideboard, usually made in section and attached to the roller-beam withhinges to allow of its being turned up out of the Way in dotting. ingalong the front of the roller-beam, is held in bearings attached to thatbeam and has slips connecting it with the guide-board J, by which allthe sections of the board can be raised at once by turning the bar, asin Fig. 3.

C is the ring-rail, supported on the vertical rods K, that slide up anddown in holes in the stationary spindle-rail B and lower rail D. A catchII, consisting of a vertical bar bent in a semicircular shape at the topand having its lower end turned back at an angle to its middle portion,is held at its lower end on a pivot 01 in a step It, bolted to the lowerrail D, preferably; but it may be attached to the under side of thespindle-rail A rod a, extend- B, if desired. This catch H is made of theproper length so that when the ring-rail G is clear down its upper endwill swing over and rest on the middle of the ring-rail, as seen inFig. 1. It has an adjustable weight 8 on its back or lower end thatthrows the catch back free from the rail 0, as shown. by the dottedlines, when not held forward by the arm F.

P is the bar that holds the separator-blades c. It is held on bearingsat 0, so as to be capable of making a quarter-turn and hold theseparators in a horizontal position when the machine is in operation(see dotted lines in Fig. l) or turned up out of the way when doftlng,as shown in the full lines. This bar P is made of a flat bar having aflange on each edge for strength and to receive the nuts of the boltsthat fasten the separatorblade to it between the flanges out of the wayand so they will not turn. To this bar P an arm F is attached, having apin 01 in its free end so that when theseparator-bar is turned up withthe separators for doffing the arm F will swing down and push the catchII by the pin t' over from the position shown in dotted lines to thatshown over the ring-rail and hold it there until the bar P is turned outto a horizontal position again, when the arm F will be raised and thecatch H. free to be thrown back by the weight 8 on its lower end.

The arm F may be put on the red at, that raises the guide-boards J,instead of the bar P, so that when that rod is turned to raise theguide-boards to dofi": the arm F will be turned down and push the catch1-1 over the ring-rail in the same Way as when the arm is attached tothe bar P, as described.

The operation of the mechanism may be described as follows: To doff, thefirst thing to do after the machine has stopped is to depress thering-rail, whichis usually done by putting the foot on the weight-lever(not shown) that raises the ring-rail and pushing that rail clear down.Then the separator-bar P is turned up with the blades and the rod aturned to raise the guide-boards out of the Way of the bobbins to betaken off of the spindles. In case the arm F is on the separator-bar Pit will be turned down and push the catch 1-1 over the ring-rail andhold it there, or if the arm is on the rod or, it will operate exactlyin the same way. When the doffing is done, the foot is again placed onthe weight-lever, the rod a and the bar P are turned down, which raisesthe arm F,whether on the rod or bar, and leaves the catch H free to bethrown back by the weight 8, and the ring-rail is allowed by the foot torise easily to place again. I

Having thus described my improvements, I claim as my invention anddesire to secure by Letters Patent 1. In a spinning frame, thecombination with the ring-rail, of a curved catch pivoted to one of thestationary rails below the ringrail, and a movable rod or arm connectedto the same moving part of the machine above the catch for pushing thehooked end of the catch over the ring-rail when that rail is depressedfor the purpose of doffing, substantially as described.

2. In a spinning-frame, the combination with the ring-rail, of a curvedcatch pivoted to one of the stationary rails below the ringrail, theseparators and the separator-bar to which the separators are secured anarm attached to the separator-bar and arranged to push the hooked end ofsaid catch over the ring-rail when the.separators are turned up out ofthe way for doffing, substantially as described.

3. In a spinning-frame, the ring-rail, vertical rods upon which thering-rail is placed, and a pivoted weighted catch having its upper endbent into a circular shape, and its lower end adapted to receive aweight, combined with the separator-bar, separators secured thereto, andan arm which extends downwardly from above the catch, and which byhearing against the catch holds its upper end pressed forward over thetop of the ringrail, substantially as set forth.

4. In a spinning-frame, the separator-bar, the pivoted arm upon whichthe separatorbar is secured, and which arm has its lower end adapted toengage with the catch, and the separators secured to the top of the bar,combined with the ring-rail, the rods upon which it is placed, and apivoted weighted catch having its upper end adapted to catch over thetop of the ring-rail, and which catch is operated by the pivoted arm,substantially as specified.

In testimony whereof I have hereunto set my hand this 25th day ofSeptember, A. D. 1897.
